So, taking the unit to receive 850, 900 MHz freuquences, how well
would it receive 2.4 GHZ frequences?

If it is vertical and omnidirectional, it will probably
become an end-fire antenna at the higher frequencies.
That means it will likely be directional but mostly
in an up direction. The same thing happens when
a 19 inch vertical whip is used on 440 MHz.
